UNIVERSAL ROLLING-TRAIN.

SPECIFICATION forming part of Letters Patent No. 399,726, dated March19, 1889. Application filed January 7, 1889. Serial No. 295,606. (Nomodel.)

To coZZ whom it may concern.-

Be it known that I, WILHELM BANSEN, a subject of the King of Prussia,German Emperor, and a resident of Kattowitz, Upper Silesia, in the Stateof Prussia, German Empire, have invented certain new and usefulImprovements in Universal Rollin gTrains for Roundand Square Iron, ofwhich the following is a full and clear description.

My invention relates to improvements in universal rolling-trains forrolling round and square iron; and it consists in placing a number ofordinary universal rolls one behind the other, so that round or squarebar-iron may be rolled from the slab in one operation at a great savingas compared. with the old in ethod.

In order to make my invention more clear, I refer to the accompanyingdrawings, in which similar letters denote similar parts throughout thedifferent figures.

Figure 1 is a top view of my improved universal rolling-train. Fig. 2 isa longitudinal section of the same. Fig. 3 is a vertical crosssectionthrough the line A B, Fig. 2. Fig. 4c is a sectional view, on a largerscale, of the guides between each set of rolls. Fig. 5 is a crosssectionthrough the line S, Fig. 4. Fig. 6 is a horizontal section. Fig. 7 is anend elevation of the driving-gear. Fig. 8 is a vertical section throughthe line E y, Fig. 7. Fig. 9 is a view of the different stages throughwhich round iron passes in passing through my improved universalrolling-train. Fig. 10 is a view of the different stages through whichsquare iron passes in passing through my improved universalrolling-train. Figs. 11 and 12 show the relative position of thevertical and horizontal rolls.

In the manufacture of small bar-iron namely, that under one and one-halfinch a large number of skilled hands are required, as each bar has to beconveyed by hand from one roll to the next smaller and entered into thematrix in the smaller rolls, and held in position by the hand during theoperation of reducing but in my improved universal rolls this manuallabor is dispensed with, as the rod isheld in the proper position by theguides which are placed before each pair of rolls. Consequently it isclear that by this process much valuable time is saved and fewer workmenare required for the same work.

In my process the rough bar is led into the first pair of rolls by theworkmen, and from this conducted to the next pairs of rollsautomatically, where the complete process of rolling is gone through. Inorder to guide the bar from one pair of rolls to the next wlthout theaid of manual labor, there are guides fitted, through which the iron rodpasses, and before every pair of rolls, with the exception of the firstpair, there is a pair of vertical revolving plain rolls, which reducethe section of the bar before it enters the horizontal rolls.

The rolls A A, which have the largest grooves, are placed first in thetrain, Flgs. l and 2, and then the second, third, and fourth pair, inthe order of the size of their grooves. Between each pair of rolls is aguide fitted, Figs. 4:, 5, and 6, which guides the rods from one roll tothe next. The guide consists of the V-blocks s s, which are held firmlyin their position on the face-plates The blocks 8 s are covered on thetop by the hinged cover, which can be lifted by the rod which is beingrolled, when the front roll dellvers more than the following roll candraw in, Flg. 4:. Just in front of the second, third, and fourth pair ofhorizontal rolls are placed the vertical fiatteningrolls B B B B B BThese vertical flattening-rolls are so arranged that they fit into theguides and compress the bar of iron si'dewise as it passes through,Figs. 9 and 10.

The vertical rolls and the guides to w, which are placed close in frontof the horizontal rolls, prevent the rod from turning, which is of greatimportance in rolling bar-iron.

The speed of the rolls A A A AB B, &c., is so regulated to each otheraccording to the size of the different grooves that the following rollalways takes the iron from the preceding one, and they are driven by thecogwheels Z) 19' b.

The plain vertical rolls B B B B 13 13 are driven from the cones O G G OC O. The cones C C drive the shafts c e 6 to which are fitted theconical wheels cl d d d d (1 These wheels gear into conical wheels d d dd d d on the shafts of the vertical rolls.

If each pair of horizontal grooved rolls A A A A &c., has a speed oftwenty-five per cent. more than that of the foregoing pair,

tween each pair of rolls, the workman knows that the grooves in therolls are set right and no injurious strain is brought to bear on therod being rolled;

The vertical rolls B B to B B are set in the following manner, both whenrolling round and square iron: Two screws, f f ,are fitted in theframe-work of the rolls, Fig.

7 one above and the otherbelow. The ends of the same are fitted withchain-wheels h h,

which are connected together by the chain 6. The bearings k of thevertical rolls are also guided by the guide-rod g, which runs parallelto and behind the screw f. The nuts Z Z are fitted to the top and bottomof the vertical rolls in the bearings 70 7c. The nuts Z Z are held faston the screws ff by the locknuts m m. The bearings Zr are slotted infront at n, and can be pressed together by the screws 0 0, so as toprevent the nuts Zfrom turning in the bearings 70.

In order, for example, to move theleft-hand vertical roll,B, to the leftand to' leave the right-hand one stationary, the screws 0 o of theright-nan d bearings, 7c, are loosened and those of the left-handbearings tightened up. The lock-nuts m m of the left-hand bearings areloosened and the nuts on the left-hand side of the left-hand bearingsscrewed so far back as is required to move the left-hand vertical roll,B The screws f and f are now revolved till theleft-han'd bearings abutagainst the displaced lock-nut on the left-hand side, and the right-handlock-nuts are tightened up, and the screws 0 0 of the right-handbearings, 7c 7r, screwed up again.

The process of rolling round bar-iron in my improved universalrolling-train is as follows: The trains of rolls A A A, &c., are so setthat the grooves are in the proper proportion. The vertical plain rollsB B B B B B die, are now set so that they press the bar sidewise as itpasses through alittle smaller than the diameter of the grooves in thefollowing horizontal rolls. When all the rolls are set and the guides ata a fastened in place, a piece of suitable iron is. fed into the firstpair of horizontal grooved rolls A A, and leaves the same with asectionsay corresponding to I, Fig. 9. It then passes through the guidesa a to the vertical plain rolls B B, where it is pressed into the formII, Fig. '9, and passes on through the second pair of hori zontalgrooved rolls A A, where it is rolled into a smaller diameter, III, Fig.9. In the second pair of vertical plain rolls B B it receives thesection IV, Fig. 9, and so on, passing through the different rolls,receiving the sections V VI in rotation until it passes through the lastpair of horizontal rolls A A where the bar comes out finished, as inVII, Fig. 9.

Square iron is rolled in exactly the same manner; but instead of roundgrooves in the horizontal rolls square grooves are used. A piece ofsuitable iron is fed into the first pair of horizontal grooved rolls AA, and leaves the same with a sectionsay corresponding to I, Fig. 10. Itthen passes through the guides a 0b to the vertical plain rolls B B,where it is pressed into the form II, Fig. 10, and passes on through thesecond pair of horizontal grooved rolls A A, where it is rolled into asmaller diameter, III, Fig. 10. In the second pair of vertical plainrolls B B it receives the section IV, Fig. 10, and so on, passingthrough the different rolls, receiving the sections V VI in rotationuntil it passes through the last pair of horizontal rolls A A, where thebar comes out finished, as in VII, Fig. 10.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent of the United States, is
